Phantom Sail

This spell summons up a ghostly sail that attaches itself to the ship (no mast is required). The phantom sail acts just as a normal sail, and is great for those times when a ship loses a sail or a mast. The spell is adaptable to form a phantom rudder, phantom keel, phantom steering wheel, etc. It cannot form a phantom hull, however. The phantom sail lasts for as long as the caster can maintain concentration.

The material component (consumed) is a small model of the equipment to be replaced.
